3、在训练阶段的model.fit之前加载先前保存的参数 ifos.path.exists(filepath): model.load_weights(filepath)#若成功加载前面保存的参数,输出下列信息print("checkpoint_loaded") 4、在model.fit添加callbacks=[checkpoint]实现回调 model.fit_generator(data_generator_wrap(lines[:num_train], batch_size, input_s...

model.set_weights()#从numpy array里将权重载入给模型,要求数组具有与model.get_weights()相同的形状。 # 查看model中Layer的信息 model.layers 查看layer信息 ###6、模型保存与加载 代码语言:javascript 复制 model.save_weights(filepath)# 将模型权重保存到指定路径,文件类型是HDF5(后缀是.h5) model.load_weig...
使用model.save()函数搭配tf.keras.models.load_model()对模型的架构,权重以及配置进行保存与恢复。 模型的保存代码如下: importtensorflow as tfimportos# 环境变量的配置os.environ['TF_XLA_FLAGS']='--tf_xla_enable_xla_devices'os.environ['TF_FORCE_GPU_ALLOW_GROWTH']='true'# 数据的加载(train_images...
Keras save_weights与ModelCheckpoint的差异 、 我通过两种方式保存keras模型1。"ModelCheckpoint“2."save_weights”训练后模型 但是当使用"load_weights“和"predict”加载训练模型时,这两种方法的性能是不同的。我的代码如下 训练和保存模型 model_checkpoint = ModelCheckpoint("Model_weights.hdf5 浏览63提问于...
首先import_meta_graph,这里填的名字meta文件的名字。然后restore时,是检查checkpoint,所以只填到checkpoint所在的路径下即可,不需要填checkpoint,不然会报错“ValueError: Can’t load save_path when it is None.”。 后面根据具体例子,介绍如何利用加载后的模型得到训练的结果,并进行预测。
load_weights(checkpoint, by_name=True) for layer, initial in zip(model.layers, initial_weights): weights = layer.get_weights() if weights and all(tf.nest.map_structure(np.array_equal, weights, initial)): print(f'Checkpoint contained no weights for layer {layer.name}!') shouldn't the ...
ModelCheckpoint(checkpoint_path, save_weights_only=False, verbose=1) history = model.fit(x_train, y_train, batch_size=64, epochs=3, validation_data=(x_val, y_val), verbose=2, callbacks=[cp_callback]) With checkpointing added, the training looping becomes what is shown in Figure 4-6...
The pretrained weights for this model are stored in a checkpoint file which I extract using the following code: PATH_REL_META= #insert file path to checkpoint with tf.Session() as sess: #import graph saver=tf.train.import_meta_graph(PATH_REL_META) #load weights for graph saver.restore(se...
